Chemotherapy in bronchogenic carcinoma.

The effects of three different chemotherapeutic treatment regimens on the survival of one hundred inoperable lung cancer patients was studied in a randomized clinical trial. Of the patients 36 received cyclophosphamide as a single agent, 31 patients actinomycin D--vincristine combination and 33 patients cyclophosphamide--methotrexate--vincristine combination. Epidermoid carcinoma was the most sensitive to the actinomycin D--vincristine combination, whereas small cell anaplastic carcinoma responded to cyclophosphamide alone, and to the cyclophosphamide--methotrexate--vincristine combination. In spite of shrinkage of the tumour no differences were, however, observed in the survival times of the eifferent groups.
